In this episode of Christ the Center, we welcome Donald John MacLean, President of Westminster Seminary UK and trustee of the Banner of Truth Trust, for a rich conversation on James Walker's The Theology and Theologians of Scotland. Their discussion begins with an update on Westminster Seminary UK's move to Oxford and the remarkable ministry of the Reformed Colloquium in Budapest, where confessional Reformed believers from across Europe gather for fellowship, encouragement, and theological exchange. The heart of the episode focuses on Banner of Truth's newly expanded edition of Walker's classic work. MacLean explains why the book has served for decades as an indispensable guide to the Scottish theological tradition, opening up figures beyond the better-known names and tracing major themes in church history, ecclesiology, providence, the atonement, and church-state relations. Together, Camden and Donald John reflect on the historical setting of Scottish theology, the value of Walker's new footnotes and translations, and the abiding importance of visible church unity and Christ's headship over his church.
